ASCOsolenoid valves with design change letter G" or H" in the catalog number (ex. 8210G 1) have an epoxy encapsulated ASCO Red Hat II solenoid. This solenoid replaces some of the solenoids with metal enclosures and open-frame constructions. Follow these installation and maintenance instructions if your valve or operator uses this solenoid.
See separate instructions for basic valve.
DESCRIPTION
Catalog numbers 8003G and 8202G are epoxy encapsulated pull-type solenoids. The green solenoid with lead wires and 1/2Ăconduit connection is designed to meet Enclosure Type 1-General Purpose, Type 2-Dripproof, Types 3 and 3S-Raintight, and Types 4 and 4X-Watertight. The black solenoid on catalog numbers prefixed EF" or EV" is designed to meet Enclosure Types 3 and 3S-Raintight, Types 4 and 4X-Watertight, Types 6 and 6P-Submersible, Type 7 (A, B, C & D) Explosionproof Class I, Division 1 Groups A, B, C, & D and Type 9 (E, F, & G)-Dust-Ignitionproof Class II, Division 1 Groups E, F & G. The Class II, Groups F & G Dust Locations designation is not applicable for solenoids or solenoid valves used for steam service or when a class H" solenoid is used. See Temperature Limitations section for solenoid identification and nameplate/retainer for service. When installed just as a solenoid and not attached to an ASCO valve, the core has a 0.250-28 UNF-2B tapped hole, 0.38 or 0.63 minimum full thread.
NOTE: Catalog number prefix EV" denotes stainless steel construction.
Catalog numbers 8202G1, 8202G3, 8202G5 and 8202G7 are epoxy encapsulated push-type, reverse-acting solenoids having the same enclosure types as previously stated for Catalog numbers 8003G1 and 8003G2.
Series 8003G and 8202G solenoids are available in:
Open-Frame Construction: The green solenoid may be supplied with
1/4 spade, screw or DIN terminals. (Refer to Figure 4)
Panel Mounted Construction: These solenoids are specifically designed
to be panel mounted by the customer through a panel having a .062 to .093 maximum wall thickness. Refer to Figure 1 and section on Installation of
Panel Mounted Solenoid.
Optional Features For Type 1 - General Purpose Construction Only
Junction Box: This junction box construction meets Enclosure Types
2,3,3S,4, and 4X. Only solenoids with 1/4 spade or screw terminals may have a junction box. The junction box provides a 1/2 conduit connection,
grounding and spade or screw terminal connections within the junction box (See Figure 5).
DIN Plug Connector Kit No.K236034:Ă Use this kit only for solenoids with
DIN terminals. The DIN plug connector kit provides a two pole with grounding contact DIN Type 43650 construction (See Figure 6).
OPERATION
Series 8003G - When the solenoid is energized, the core is drawn into the solenoid base sub-assembly. IMPORTANT: When the solenoid is
de-energized, the initial return force for the core, whether developed by spring, pressure, or weight, must exert a minimum force to overcome residual magnetism created by the solenoid. Minimum return force for AC construction is 11 ounces, and 5 ounces for DC construction.
Series 8202G - When the solenoid is energized, the disc holder assembly seats against the orifice. When the solenoid is de-energized , the disc holder assembly returns. IMPORTANT: Initial return force for the disc or disc
holder assembly, whether developed by spring, pressure, or weight, must exert a minimum force to overcome residual magnetism created by the solenoid. Minimum return force is 1 pound, 5 ounces.
MM All Rights Reserved.
Check nameplate for correct catalog number, service, and wattage. Check front of solenoid for voltage and frequency.
WARNING: Electrical hazard from the accessibility of live parts. To prevent the possibility of death,Ăserious injury or property damage, install the open - frame solenoid in an enclosure.
FOR BLACK ENCLOSURE TYPES 7 AND 9 ONLY
INSTALLATION
CAUTION: To prevent fire or explosion, do not install solenoid and/or valve where ignition temperature of hazardous atmosphere is less than 165 C. On valves used for steam service or when a class H" solenoid is used, do not install in hazardous atmosphere where ignition temperature is less than 180C. See nameplate/retainer for service.
NOTE: These solenoids have an internal non-resetable thermal fuse to limit solenoid temperature in the event that extraordinary conditions occur which could cause excessive temperatures. These conditions include high input voltage, a jammed core, excessive ambient temperature or a shorted solenoid, etc. This unique feature is a standard feature only in solenoids with black explosionproof/dust-ignitionproof enclosures (Types 7 & 9).
CAUTION: To protect the solenoid valve or operator, install a strainer or filter, suitable for the service involved in the inlet side as close to the valve or operator as possible. Clean periodically depending on service conditions. See ASCO Series 8600, 8601, and 8602 for strainers.
Temperature Limitations
For maximum valve ambient temperatures, refer to chart. The temperature limitations listed, only indicate maximum application temperatures for field wiring rated at 90C. Check catalog number prefix and watt rating on nameplate to determine maximum ambient temperature. See valve installation and maintenance instructions for maximum fluid temperature. NOTE: For steam service, refer to Wiring section, Junction Box for temperature rating of supply wires.

Positioning
This solenoid is designed to perform properly when mounted in any position. However, for optimum life and performance, the solenoid should be mounted vertically and upright to reduce the possibility of foreign matter accumulating in the solenoid base sub-assembly area.
Wiring
Wiring must comply with local codes and the National Electrical Code. All solenoids supplied with lead wires are provided with a grounding wire which is green or green with yellow stripes and a 1/2 conduit connection. To

facilitate wiring, the solenoid may be rotated 360. For the watertight and explosionproof solenoid, electrical fittings must be approved for use in the approved hazardous locations.
CAUTION: Cryogenic Applications - Solenoid lead wire insulation should not be subjected to cryogenic temperatures. Adequate lead wire protection and routing must be provided.
Additional Wiring Instructions For Optional Features:
Open-Frame solenoid with 1/4 spade terminals.
For solenoids supplied with screw terminal connections use #12-18 AWG stranded copper wire rated at 90C or greater. Torque terminal block screws to 10 ± 2 in-lbs [1,0 ± 1,2 Nm]. A tapped hole is provided in the solenoid for grounding, use a #10-32 machine screw. Torque grounding screw to 15 - 20 in-lbs [1,7 - 2,3 Nm]. On solenoids with screw terminals, the socket head screw holding the terminal block to the solenoid is the grounding screw. Torque the screw to 15 - 20 in-lbs [1,7 - 2,3 Nm] with a 5/32 hex key wrench.
Junction Box
The junction box is used with spade or screw terminal solenoids only and is provided with a grounding screw and a 1/2 conduit connection. Connect #12-18 AWG standard copper wire only to the screw terminals. Within the junction box use field wire that is rated 90C or greater for connections. For steam service use 105C rated wire up to 50 psi or use 125C rated wire above 50 psi. After electrical hookup, replace cover gasket, cover, and screws. Tighten screws evenly in a crisscross manner.
DIN Plug Connector Kit No.K236034
1. The open-frame solenoid is provided with DIN terminals to
accommodate the plug connector kit.
2. Remove center screw from plug connector. Using a small screwdriver, pry
terminal block from connector cover.
3. Use #12-18 AWG stranded copper wire rated at 90C or greater for
connections. Strip wire leads back approximately 1/4for installation in socket terminals. The use of wire-end sleeves is also recommended for these socket terminals. Maximum length of wire-end sleeves to be approximately 1/4.ĂTinning of the ends of the lead wires is not recommended.
4. Thread wire through gland nut, gland gasket, washer and connector cover. NOTE: Connector housing may be rotated in 90 increments from position shown for alternate positioning of cable entry.
5. Check DIN connector terminal block for electrical markings. Then make
electrical hookup to terminal block according to markings on it. Snap terminal block into connector cover and install center screw.
6. Position connector gasket on solenoid and install plug connector. Torque
center screw to 5 ± 1 in-lbs [0,6 ± 1,1 Nm].
NOTE: Alternating current (AC) and direct current (DC) solenoids are built differently. To convert from one to the other, it may be necessary to change the complete solenoid including the core and solenoid base sub-assembly, not just the solenoid. Consult ASCO.
Installation of Solenoid
Solenoids may be assembled as a complete unit. Tightening is accomplished by means of a hex flange at the base of the solenoid.
Installation of Panel Mounted Solenoid (See Figure 1)
1. Disassemble solenoid following instruction under Solenoid Replacement
then proceed.
2. Install solenoid base sub-assembly through customer panel.
3. Position spring washer on opposite side of panel over solenoid base
sub-assembly.
4. Replace solenoid, nameplate/retainer and red cap.
5. Make electrical hookup, see Wiring section.
Solenoid Temperature
Standard solenoids are designed for continuous duty service. When the solenoid is energized for a long period, the solenoid becomes hot and can be touched by hand only for an instant. This is a safe operating temperature.
MAINTENANCE
WARNING: To prevent the possibility of death, serious injury or property damage, turn off electrical power, depressurize solenoid operator and/or valve, and vent fluid to a safe area before servicing.
Cleaning
All solenoid operators and valves should be cleaned periodically. The time between cleaning will vary depending on medium and service conditions. In general, if the voltage to the solenoid is correct, sluggish valve operation, excessive noise or leakage will indicate that cleaning is required. Clean strainer or filter when cleaning the valve.
Preventive Maintenance
Keep the medium flowing through the solenoid operator or valve as free
from dirt and foreign material as possible.
While in service, the solenoid operator or valve should be operated at least
once a month to insure proper opening and closing.
Depending on the medium and service conditions, periodic inspection of
internal valve parts for damage or excessive wear is recommended. Thoroughly clean all parts. Replace any worn or damaged parts.
Causes of Improper Operation
Faulty Control Circuit: Check the electrical system by energizing the
solenoid. A metallic click signifies that the solenoid is operating. Absence of the click indicates loss of power supply. Check for loose or blown fuses, open-circuited or grounded solenoid, broken lead wires or splice connections.
Burned-Out Solenoid: Check for open-circuited solenoid. Replace if
necessary. Check supply voltage; it must be the same as specified on nameplate/retainer and marked on the solenoid. Check ambient temperature and check that the core is not jammed.
Low Voltage: Check voltage across the solenoid leads. Voltage must be at
least 85% of rated voltage.
Solenoid Replacement
1. Disconnect conduit, coil leads, and grounding wire. NOTE: Any optional parts attached to the old solenoid must be reinstalled on the new solenoid. For 3-way construction, piping or tubing must be removed from pipe adapter.
2. Disassemble solenoids with optional features as follows:
Spade or Screw Terminals
Remove terminal connections, grounding screw, grounding wire, and
terminal block (screw terminal type only). NOTE: For screw terminals, the socket head screw holding the terminal block serves as a grounding screw.
Junction Box
Remove conduit and socket head screw (use 5/32 hex key wrench) from
center of junction box. Disconnect junction box from solenoid.
DIN Plug Connector
Remove center screw from DIN plug connector. Disconnect DIN plug
connector from adapter. Remove socket head screw (use 5/32 hex key
wrench), DIN terminal adapter, and gasket from solenoid.
3. Snap off red cap from top of solenoid base sub-assembly. For 3-way
construction with pipe adapter (Figure 3), remove pipe adapter,
nameplate and solenoid. Omit steps 4 and 5.
4. Push down on solenoid. Then using a suitable screwdriver, insert blade
between solenoid and nameplate/retainer. Pry up slightly and push to
remove. NOTE: Series 8202G solenoids have a spacer between the nameplate/ retainer and solenoid.
